1.We are devoted to the meticulous manufacturing and dedicated supply of premium elastic rail clip products, specifically engineered for railway applications. Utilizing superior quality raw materials, these elastic rail clips exhibit high precision engineering, delivering unparalleled tensile strength and exceptional corrosion resistance. Moreover, our products are highly customizable to meet client-specific requirements, all at a client-preferred price.
Renowned within the railway industry, our elastic rail clips provide unmatched clamping performance, ensuring secure rail attachment with effortless installation.
Leveraging out-of-patent technologies from industry giants Pandrol and Vossloh, SUYU collaborates with esteemed quality manufacturers to offer a cost-effective range of elastic rail clips. These are suitable for various rail sections and applications, including selected SKL tension clamps.
With rigorous dimensional control and the use of premium spring steel, the elastic rail clips and other railway fastenings supplied by SUYU are crafted to meet specified standards, ensuring complete customer satisfaction.
Our expertise in producing elastic rail clips for varied toe load and axle load requirements is unparalleled. Whether securing rails on wooden, steel, or concrete sleepers, we provide a range of elastic rail clips with steel bar diameters from 12mm to 20mm. We manufacture diverse elastic rail clips with flat toes for broad gauge lines, offering toe loads from 850kgf to 1100kgf, capable of meeting any toe load and axle load specifications.
Technical Specifications of the Elastic Rail Clip| Diameter | Weight (Kg) | Toe Load |
| 12mm | 0.18 | 200-400 |
| 14mm | 0.30 | 400-600 |
| 16mm | 044 | 500-700 |
| 18mm | 0.60 | 800-1000 |
| 20mm | 0.78 | 1100-1400 |
When spring steel deflects by 9.1mm, it achieves a fatigue life of up to 5 million cycles without fracture.
Material: 60Si2MnA
Surface: Available in plain, black painting, and red painting finishes.
MOQ: 5000 PCS
Packing: Provided in plastic bags and wooden pallets, or customized as per clients' requirements.
2.As a leading manufacturer and exporter of the SKL tension clamp, we ensure the electric insulation of the rail on its support. These tension clamps maintain the rail elastically in both vertical and transverse directions. Featuring a support table for the rail, projecting shoulders, an interposed pad, an insulating clip, elastically yieldable strips, and fixing equipment, our product guarantees a reliable and secure fit.
Our elastic rail clip is engineered as a boltable clip with superior permanent clip strength. Designed for rail construction with concrete sleepers, our clips range in diameter from 13mm to 15mm, including SKL1, SKL2, SKL3, SKL12, SKL14, SKL21, and SKL30.
| Diameter | Type | Weight (Kg) |
| 13mm | SKL1 | 0.49 |
| 13mm | SKL3 | 0.53 |
| 13mm | SKL12 | 0.53 |
| 13mm | SKL14 | 0.505 |
Fatigue Property: Endures no less than 5 million cycles.
Loading Property: Under a pressure range of 8-12KN, the displacement ranges between 9-12mm.
Material: 60Si2CrA
Surface: Available in plain, black painting, and red painting finishes.
